please give me some idea what to do and how to do

i guess, you should replace
msgList = MsgJSONParser.parseData(response);
MsgAdapter adapter = new MsgAdapter(ListMessage.this, msgList);
with
msgList = MsgJSONParser.parseData(response);
ArrayList<Msg_data> userList=new ArrayList();
for (int i=0;i<msgList.size();i++){
if (!userList.contains(msgList.get(i)))
userList.add(msgList.get(i));
else {
int index=userList.indexOf(msgList.get(i));
if (userList.get(index).compareTo(msgList.get(i))>0)
userList.add(msgList.get(i));
}
}
MsgAdapter adapter = new MsgAdapter(ListMessage.this, userList);`
and implement Comparable and override equals method in your Msg_data class
public class Msg_data implements Comparable {
public int id;
public String user_id;
public String user_name;
public String message;
public String is_read;
public String image_link;
public String created_at;
public String from;
public String to;
public String getFrom() {
return from;
}
public void setFrom(String from) {
this.from = from;
}
public String getTo() {
return to;
}
public void setTo(String to) {
this.to = to;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUser_id() {
return user_id;
}
public void setUser_id(String user_id) {
this.user_id = user_id;
}
public String getUser_name() {
return user_name;
}
public void setUser_name(String user_name) {
this.user_name = user_name;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public String getIs_read() {
return is_read;
}
public void setIs_read(String is_read) {
this.is_read = is_read;
}
public String getImage_link() {
return image_link;
}
public void setImage_link(String image_link) {
this.image_link = image_link;
}
public String getCreated_at() {
return created_at;
}
public void setCreated_at(String created_at) {
this.created_at = created_at;
}
public Msg_data() {
}
public Msg_data(int id) {
this.id = id;
}
#Override
public boolean equals(Object obj) {
try
{
return (this.getUser_id().equals(( (Msg_data)obj).getUser_id()));
}
catch(NullPointerException e){
return false;
}
}
#Override
public int compareTo(#NonNull Object o) {
SimpleDateFormat simpleDateFormat=new SimpleDateFormat("your pattern here");
try {
Date date=simpleDateFormat.parse(created_at);
Date dateOtherObject=simpleDateFormat.parse(((Msg_data)o).getCreated_at());
return date.compareTo(dateOtherObject);
}
catch (ParseException e){
return -1;
}
}
something like this:) Dont forget replace simple date format in compare method

RecyclerView to Firebase database

I actually want cardView in my RecyclerView to retrieve data from firebase but it returns error. Please do help me to attach my RecyclerView to firebase and retrieve data from it.
Thanking you in advance.
Here is the mainActivity.java
mbloglist = findViewById(R.id.rv1);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(this);
productAdapter adapter = new productAdapter(this);
mbloglist.setLayoutManager(layoutManager);
mbloglist.setAdapter(adapter);

database1 = FirebaseDatabase.getInstance();
myRef = database1.getReference("Users");
Toast.makeText(getApplicationContext(),"Database Done",Toast.LENGTH_SHORT).show();
myRef.addValueEventListener(new ValueEventListener() {

Here is the Firebase Realtime Database Image

ModelClass class and your database doesn't have the same structure, because in your database you have a new node called "phone" inside each userID node.
You can try 3 approaches to solve this issue:
a.) Write data in your database just like ModelClass is, without "phone" node.
b.) Create a new class called "Phone" with same attributes you have inside "phone" node in the database, and make this new class part of ModelClass class.
c.) On myRef onDataChange method, inside for statement, check for each child key and fill ModelClass atributes one by one. When the child key is equal to "phone", start a new loop statement in "phone" children to fill these attributes.

Add the following code:
#Override
public int getItemCount() {
return productList.size();
}

Don't know where I did Mistake,Please Help me to findout that,Thanks in Advance.

You class members should never be declared static as you have done here -
public class OrderApprovalDetails
{
public static String date,orderid,shopname,ownername,mobile,location,itemscount,amount;
change this to
public class OrderApprovalDetails
{
public String date,orderid,shopname,ownername,mobile,location,itemscount,amount;

Answer Class
public class Answer {
Long id;
Long userId;
Long questionId;
String description;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public Long getUserId() {
return userId;
}
public void setUserId(Long userId) {
this.userId = userId;
}
public Long getQuestionId() {
return questionId;
}
public void setQuestionId(Long questionId) {
this.questionId = questionId;
}
public String getDescription() {
return description;
}
public void setDescription(String description){
this.description = description;
}
}

You need to implement/override public String toString() method in Answer class.
#Override
public String toString() {
return description;
}
